Aderaba, Mawell's demon was merely a THOUGHT experiment to explain how you could not DECREASE entropy in a system automatically. That Rambam says the demon does not exist is, in fact, upholding the laws of thermodynamics, namely that entropy always increases within a system. The only time we see order arise from entropy is when the process of doing so comes from Hashem (creation ex nihilo)!
